Application filed December 14, 1920. Serial No. 430,705.

To all whom it may concern:

Be it known that I, Grnno Mrsnnoccm, a

d subject of the King of Italy, residing at Philadelphia. in the county of Philadelphia and State ofPennsylvanla, have invented certain new and useful Improvements in Concrete Railway-Ties, of which the following is a specification.

The principal objects of the present invention are, first, to avoid breakage of the ties while providing the necessary strength and resiliency, and second, to facilitate the attachment and removal of the screws, bolts or fastenings by which the rails are secured to the ties.

Other objects of the invention will appear from the following description and the invention will be claimed at the end hereof. The description will be given in connection with the accompanying drawings, forming part hereof, and in which-- Figure 1, is an elevational view, partly in section, and with part of the concrete omitted, of one end of a railway tie embodying features of the invention.

Fig. 2 is a similar view in plan.

Fig. 3, is a view of the bottom of the tie, and 7 Figs. 4 and 5, are sectional views on the lines 4 -4 and 5-5 of Fig. 1.

In the drawings 1 are box-like metal castings or structures, shown as of generally T- shape or form in plan and they are provided at different levels with spaced rectangular openings 2. of two dimensions or sizes so as to provide a seat 3, and the openings flextcnd clear through the tie in which the parts 1 are embedded. There are two sets or series of longitudinal reinforcing rods. One set comprises two pairs of straight rods 4 and 5. shown as circular in cross-section and provided at their ends with hooks 6 ranging vertically, and the rods of each pair pass on opposite sides of the structures 1 and extend one below the other from end to end of the tie, the pair of rods at being embedded near the top of the tie and the pair of rods 5 being embedded beneath the rods 4 andnear the bottom of the tie. The other set of reinforeements comprises a pair of rods 7, shown as circular in cross section, and they are not straight, but are offset to lie parallel with the rods 4 at the ends of the tie and to pass down into parallelism with the rods 5 and under the structure 1. These rods 7 also have hooked ends (3, and they are embedded in the tie and pass to each side of the structure 1. 8 are tie wires wound around the various rods and embedded in the tie and crossed upon themsel ves, Fig. 4. 9 are screws or. bolts by means of which the rails are secured to the ties and they are equipped with heads 10 adapted to enter the small openings 2, when alined therewith and to be turned into engagement with the seats 3. 11 are lead or leaden plates throughwhich the bolts 9 pass and by which the rails are supported, and they serve to protect the 'tie from the shocks and jam 10f passing trains. In the event of the breakage of the bolts 9, it is evident that they can be removed and replaced from the bottom of the tie and through the openings 2, Without removing the tie. i

I claim:

The combination of two metal box-like structures each of T-shape in plan and each having clear through it rectangular open ings of two dimensions at different levels and of which the bottoms of the openings at the lower level constitute angular seats, a reinforced concrete tie in which the two structures are embedded and which is provided with openings alined with the openings in the structure, and bolts having heads engaging the seats and passable clear through the tie from both the top and bottom thereof.
